Monoterpene Suppression

Monoterpene Suppression refers to cannabis lines that exhibit notably reduced volatile monoterpene production relative to their genetic background or parent strains. These plants typically show lower concentrations of limonene, myrcene, pinene, and other single-ring terpenes, often producing a muted or atypical aroma profile. Monoterpene suppression can occur through selective breeding, environmental factors, or naturally occurring genetic variation affecting terpene synthase expression. Breeders have identified lines demonstrating this trait across multiple chemotypes, though the genetic mechanisms underlying consistent suppression remain an active area of cannabis research. This family is distinct from high-terpene or terpene-dominant strains, representing an alternative breeding direction for cultivation and breeding programs.

Breeders working with monoterpene-suppressed lines often pursue them for programs seeking low-aroma phenotypes, cannabinoid-dominant profiles, or novel terpene expression patterns. Understanding suppression mechanisms helps guide selection for stability across generations and crosses with complementary genotypes.
